How to receive additional data for Push notification in ionic2

I have below payload which i am sending as push notification where ClientID is additional data:

$msg = array
(
‘message’ => ‘here is a message. message’,
‘title’ => ‘This is a title. title’,
‘subtitle’ => ‘This is a subtitle. subtitle’,
‘tickerText’ => ‘Ticker text here…Ticker text here…Ticker text here’,
‘vibrate’ => 1,
‘sound’ => 1,
‘largeIcon’ => ‘large_icon’,
‘smallIcon’ => ‘small_icon’,
‘ClientID’ => ‘CT 123456’
);

So in ionic2, while receiving in the app.ts file in function

push.on(‘notification’, (data) => { };

how to receive this additional ClientID passed from the server in ionic2 typescript?

I gone through the below reference but not helpful.

It’s giving module error.

Thanks
